Why doesn't ArrayDataProvider pass id for edit?

Question

Yii

I formatted the data from the database in the ArrayDataProvider, passed it to the widget, but the edit link does not pass the record id to the database, but the record index in the ArrayDataProvider array.
How can I specify that the right id is taken?

Answer 1

Everything, it turns out, is in the dock, I didn't read it)
To do this, you need to set 'key' => 'id' in ArrayDataProvider;

Answer 2

1) you can rewrite the button.
2) you can use indexBy('id')
3) I'm not sure, but doesn't the standard data provider eat an array?
